    • The phylogenetic systematics of Spilomelinae and Pyraustinae (Lepidoptera: Pyraloidea: Crambidae) inferred from DNA and morphology 

      Mally, Richard; Hayden, James E.; Neinhuis, Christoph; Jordal, Bjarte Henry; Nuss, Matthias (Peer reviewed; Journal article, 2019)
      Spilomelinae and Pyraustinae form a species-rich monophylum of Crambidae (snout moths). Morphological distinction of the two groups has been difficult in the past, and the morphologically heterogenous Spilomelinae has not ...

      The first typification of Lepra Scop. by Pertusaria discoidea (Pers.) Malme (= Lepra albescens (Hudson) Hafellner), made in the Paris Code (1956), is shown to be correct after studies of the original material in the Micheli ...
    • Patterns of coevolution of ambrosia beetle mycangia and the Ceratocystidaceae, with five new fungal genera and seven new species 

      Mayers, CG; Harrington, TC; Masuya, H; Mcnew, DL; Jordal, Bjarte Henry; Shih, H-H; Roets, F; Kietzka, GJ (Peer reviewed; Journal article, 2020)
      Ambrosia beetles farm specialised fungi in sapwood tunnels and use pocket-like organs called mycangia to carry propagules of the fungal cultivars. Ambrosia fungi selectively grow in mycangia, which is central to the ...

      Gondwanoscurus curleri sp. nov. is described based on four males collected in November 1990 and April 1991 in the West Usambara Mountains, Tanzania. It is the first species of Gondwanoscurus Ježek, 2001 to be described ...
    • Deceleration of morphological evolution in a cryptic species complex and its link to paleontological stasis 

      Cerca, Jose; Meyer, Christian; Stateczny, Dave; Siemon, Dominik; Wegbrod, Jana; Purschke, Günter; Dimitrov, Dimitar; Struck, Torsten H (Peer reviewed; Journal article, 2020)
      Morphological stasis or the absence of morphological change is a well-known phenomenon in the paleontological record, yet it is poorly integrated with neontological evidence. Recent evidence suggests that cryptic species ...
    • Drivers of large‐scale geographical variation in sexual systems of woody plants 

      Wang, Yunyun; Lyu, Tong; Shrestha, Nawal; Lyu, Lisha; Li, Yaoqi; Schmid, Bernhard; Freckleton, Robert; Dimitrov, Dimitar; Liu, Shuguang; Hao, Zhanqing; Wang, Zhiheng (Peer reviewed; Journal article, 2020)
      Aim: Sexual systems strongly influence angiosperm evolution and play important roles in community assembly and species responses to climate change. However, geographical variation in proportions of different sexual systems ...
    • First record of avian extinctions from the Late Pleistocene and Holocene of Timor Leste 

      Meijer, Hanneke; Louys, Julien; O'Connor, Sue (Peer reviewed; Journal article, 2019)
      Timor has yielded the earliest evidence for modern humans in Wallacea, but despite its long history of modern human occupation, there is little evidence for human-induced Late Pleistocene extinctions. Here, we report on ...
    • Parthenogenetic vs. sexual reproduction in oribatid mite communities 

      Maraun, Mark; Caruso, Tancredi; Hense, Jonathan; Lehmitz, Ricarda; Mumladze, Levan; Murvanidze, Maka; Nae, Ioana; Schulz, Julia; Seniczak, Anna Beata; Scheu, Stefan (Peer reviewed; Journal article, 2019)
      The dominance of sex in Metazoa is enigmatic. Sexual species allocate resources to the production of males, while potentially facing negative effects such as the loss of well‐adapted genotypes due to recombination, and ...
    • Characterization of bone surface modifications on an Early to Middle Pleistocene bird assemblage from Mata Menge (Flores, Indonesia) using multifocus and confocal microscopy 

      Meijer, Hanneke; d'Errico, Francesco; Queffelec, Alain; Kurniawan, Iwan; Setiabudi, Erick; Sutisna, Indra; Brumm, Adam; Van Den Bergh, Gerrit D. (Peer reviewed; Journal article, 2019-09-01)
      Island Southeast Asia (ISEA) is a key region for the study of human evolution. New fossil and archaeological evidence, from several islands, suggests an Early to Middle Pleistocene colonisation date by hominins. A taphonomic ...
    • An approach to determining anthocyanin synthesis enzyme gene expression in an evolutionary context: an example from Erica plukenetii 

      Le Maitre, Nicholas C.; Pirie, Michael David; Bellstedt, Dirk U. (Peer reviewed; Journal article, 2019)
      Background and Aims: Floral colour in angiosperms can be controlled by variations in the expression of the genes of the anthocyanin pathway. Floral colour shifts influence pollinator specificity. Multiple shifts in floral ...
    • The Sticta fuliginosa group in Norway and Sweden 

      Ekman, Stefan; Tønsberg, Tor; Jørgensen, Per Magnus (Peer reviewed; Journal article, 2019)

    • The dilemma of asymmetric porphyroclast systems and sense of shear 

      Zhang, Qing; Fossen, Haakon (Peer reviewed; Journal article, 2020-01)
      Asymmetric porphyroclast systems have long been used as independent shear-sense indicators based on their clast-tail asymmetry and/or stair-stepping tail geometry. Over the last two decades, advances in exploring the ...
